Abstract

L'invention concerne un corps creux absorbeur de chocs destiné à un véhicule. Ledit corps est fabriqué par moulage par soufflage de résine thermoplastique afin d'empêcher qu'une partie à paroi mince entraînant la diminution de la capacité d'absorption de choc dans un moulage par fusion ne soit produite par diminution de l'épaisseur de chacun des corps creux absorbeurs de chocs montés à l'intérieur d'éléments constitutifs d'un véhicule. Les corps creux absorbeurs de choc (1a) et (1b) présentent des parois (3) et (4) opposées, les parties d'extrémité de la pluralité de nervures creuses (5) et (6) formées par creusement des parois vers les autres parois opposées étant soudées les unes aux autres, et les deux feuilles de corps absorbeurs de chocs étant empilées l'une sur l'autre, les nervures creuses étant disposées de façon ordonnée les unes par rapport aux autres ou mécaniquement reliées les unes aux autres.
